Hi,
When you mouse over on your added "Image or feature layer" in arcview,
the scale/extent in the top right corner changes...
So to determine extent you should be able to mouse over at the four
corners of your feature and get extents...

Alternatively, you get this information from a metadata file
accompanying your shapefile.

I am trying to show my map using MapServer & PHP. However, I
can't seem to figure out how to get the extent valuies
=20
Here is my .map file
=20
MAP
NAME HELLO
IMAGETYPE PNG
STATUS ON
EXTENT 0 0 4000 3000
SIZE 400 300
=20
WEB
IMAGEPATH "/Inetpub/wwwroot/MyOwnData/tmp/"
IMAGEURL "tmp/"
END
=20
LAYER # MODIS raster layer begins here
NAME Italy
DATA "data/Italy.jpg"
STATUS DEFAULT
TYPE RASTER
PROCESSING "BANDS=3D1,2,3"
OFFSITE 71 74 65
=20
PROJECTION
"init=3Depsg:4326"
END
END # MODIS raster layer ends here
=20
END
=20
In the MapServer tutorial, it says that I can use ArcView to
determine the extent. I have ArcView, but I still can't figure out how
to get the extent in it. I've tried a couple of different values from
Area Of Interest (Display & View), but none of those seem to work
either.

Thanks for any help in advance,
Sharyn
